III. Problem Solving. Solve the following problem using the formula below. Effecient Th-TC Effecient = X100% Th For nos 1,2 and 3 - Qh-QC x 100% Qh For nos 4 and 5 E=Pt Cost = Cost per kWh x E

1. What is the efficiency of a gasoline engine that receives 155 J of energy from combustion and loose 95 J by heat to exhaust during one cycle?

2. Suppose a steam engine receives steam at 300 K. The engine uses a part of this thermal energy for work. It exhausts the rest to a condenser at a temperature of 150 K What is the maximum efficiency of this steam engine?

3. What is the efficiency of a gasoline engine that receives 355 J of energy from combustion and loose 210 J by heat to exhaust during one cycle?

4. How much electrical energy is used by a 0.35-KW Aircon for 12 hours? If the cost of electricity is Php 15.00 per kWh, how much will the use of the Aircon cost?
